CAR COUPLER.

Application filed March 1, 1924.

To all "whom it may concern:

Be it known that I, HARRY M. Bnown, residing at New Kensington, in the county of Vestmoreland and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Car Couplers, of which improvements the following is a specification.

My invention relates to improvements in car couplers, and particularly consists in a couple-r suitable for use in coupling together in a train cars adapted to be dumped lat erally. Such cars are used in mines, steel plants, and elsewhere, and for carrying various articles-coal, molten metal, etc.

The invention illustrated in the accompanying drawings. Fig. I is a view in vertical and longitudinal section of the end sill of a car having applied to it the coupler of my present invention. Fig. 11 is a view of the same, seen in plan from above. Fig. 111 is a. view in elevation of the pin which is one component of the head.

The sill 1 of the car project-s beyond the body, and, if formed of wood, as is common, may be faced with a steel plate 2. This sill 1 takes the strain of traction, and may he modified in shape, according to the knowledge of the art it may enter into and from partof the frame structure of the car, and may through the frame of the car be integrated with a coupler structure at the opposite end of the car, and so made strong to endure traction strains. All this is well known to the art, and need not be elaborated in a disclosure of this invention.

Properly secured at an interval vertically from, and preferably above the sill 1, extends astrap 3, which together with the sill forms a clevis in which the coupler struc ture is anchored. Sill and strap are penetrated by aligned and vertically extending circular holes, and through these holes anchorage is effected.

Anchorage is effected by securing for free turning in these aligned holes the pin or stud 4. As shown, this pin or stud l is essentially cylindrical, and adapted to turn freely in the aligned holes in sill and strap. It is capable not of turning merely, it has also within limits a range of vertical movement, sliding in these holes. Such vertical movement is limited by means of shoulders Serial No. 696,216.

which advantageously take the form of re movable and adjustable nuts 5 with small bearing plates 10 between.

Between the strap 3 above and the sill 1 below the pin or stud t is enlarged to form a head 6. This head as here shown is essentially cubical in form and is penetrated by horizontally extending circular bore. it will be perceived that the: head itself, movable vertically between the sill below and the strap above, may be relied upon, under proper circumstances, as the means to limit the range of vertical movement.

A coupling link 7 is provided which has, extending from one end an integral stem 8. This stem is cylindrical and it extends through and is freely rotatable within the bore described which extends horizontally through the head 6 formed upon and as part of the pin or stud l. Not only is the link 7 with its stem 8 rotatable within the head 6, it is within limits movable. longitudinally within the bore in head 6. To that end the stem 8 of the link is at its forward end shouldered, as at 9 and at its rear end is provided with a removable and adjustable nut 11 faced with a small bearing plate 12.

Consideration of the structure so illustrated and described will make plain the facts, first, that the pivoting of the pin or stud on vertical axis on the car structure adapts the coupling for the free rounding of curves, and to turning aside as well when cars are to be pushed without coupling. Second, the pivoting of the link on horizontal axis provides for the turning freely of the body of either of two coupled cars, without the necessity of uncoupling. Third, the play in. longitudinal direction of the stem of link 7 within the head 6 of the pin or stud affords the necessary slack for coupling and uncoupling and for traction. Finally, that the play in vertical direction of the pin or stud 4 within. its anchorage allows for adjustment of the coupling link in height, and the relief of strains such as may be encountered in service.

I claim as my invention:

In a coupler for cars the combination of a clevis anchored in the car body, a stud borne by said clevis rotatable in its bearings and movable longitudinally in its hearing within a limited range, and a link provided with an extended and integral stem In testimony whereof I have hereunto set and by such stein pix oted to said stud or my hand.

an axis at right an les to that on which the stud is itself i-ota table aforesaid, said HARRY BROWVN' 5 link being movable longitudinally Within a Vitnesses:
